Diallyl sulfide inhibits murine WEHI-3 leukemia cells in BALB/c mice in vitro and in vivo.

It is well documented that enhanced garlic (Allium sativum) consumption leads to decrease in the cancer incidences. Diallyl sulfide (DAS), one of the components of garlic, induces cytotoxicity and apoptosis in many cancer cell lines. The present studies are focused on the in vivo effects of DAS on leukemia WEHI-3 cells in the BALB/c mice.

Capsaicin-induced apoptosis in human hepatoma HepG2 cells.

Capsaicin, a pungent ingredient of red pepper, has been reported to possess antitumor activities. In this study, the effects of capsaicin on human HepG2 cells were investigated. Capsaicin reduced viability by PI incorporation in HepG2 cells in a dose and time dependent manner.
